IMPROVEMENT iN cAR-PusHEns.

The Schedule referred to in these Letters Patent and making part of the same car-push er.'

' Aable length.

To all lwhom 'it 'mayV concern: Beit known that I, 'RUFUS LANE, of Freeport, 1n the county of Stephenson and State of Illinois,

haveinvente'd a new and improved Gar-Pusher; and

I do hereby declare that the following is a full, clear, and exact description tlereof, which willenableothers skilled in theart to make and use the same, reference being had to the accompanying drawing forming part of this specication. v'

Figure 1 represents a side view of my improved Figure 2 is apl'an Or topV view Of the same.

4.Similar letters of reference indicate corresponding parts.

This invention relates to a new `implementffor,pro-

pelling railroad-cars on switches, 85o., in places where engines for that purpose are not `to be Obtained.

' The invention consists inthe use of' an extensioni frame, which has aclaw fOr griping` the rail at one `end, and a pushing-block at the other, and can be extended by revolving a'pinionLa-s hereinafter more fully" described. A. inthe drawing represents a'inetal tube, Ot' suit- B isa rod, with one end into the tube. l The Outer end of the ro'd B has a longitudinal slot, @through which is fitted a` pin, b, that serves as a pivot for two `levers. or jaws, G C, as shown, in fig. 1,.

The outer arms c of the levers C carry griping-pins d, as shown. Their inner arms `e` embrace a wedge, mrthat is aixed to vthe rod B.

`Thatend of the rod B, whichis concealed within thetubeA, is toothed, and meshesinto a small pinion,

f, as iudicated by dotted line-s in iig. v1.`

VThe pinion f 's mounted upon au arbor, g,` which i has its bearings ina jacketD, that is iittedupon the tube A..

Toothed wheels h 'i connect the arbor g with'a crankshat`t,j, hung iu the jacket. By turning the crank -shaft the rack will be drawn inwardiy Or outwardly, as may be desired, and the entire apparatus vconselquentlyV shortened or extended.

' The outer end` of the tube carries a block or pushingarm,-E,'which may be fastened by means of a y universal joint. i v The apparatus is applied inthe following manner: The rod, being dijawn into the tube as much as possible, the jaws C vare fittedovcr arail, so that the pins fd gripe the head of the same,.while [the block Eis placedagainst the canto he pushed. The instrument standsthus in al1 inclined position. The crank-shaft is now turned so as to extend the instrument. By

'this action the wedge m is forced between the jaws,

vcausing the same to automatically take a. rm holdv of the rail. In fact, the greater the strain, the firmer will be the-bold taken by the jaws.

As the instrument is being extended, the ca r will be pushed ahead. A suitable degree of motion can thus be be obtained. i

The power obtained by the apparatus is very considerable, so that one man can do' the work now done by six or more.

After the instrument has been extended,-itcan again be 'contracted either by.1'e\'olving'-the crankshaft, Or by pulling the rod B into the slee\'e by means Of a handle, F., inwhich case the crank mustbe thrown Out Of gear. This is effected by drawing the bolt K, which connects the crank l with its shaft,

ont Of the socket in the latter.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent 1. The extensible pusher for railroad-cars, consisting of the tube A and rod B, provided with the wedge m', the jaws C, crank-shaft, and suitable gear, substantially as herein shown and described, and for the purpose speciiied.

2. The jaws G, bolt'b, slot a, and wedge m, cornbined and arranged substantially as specified.

RUFUS LANE.
